When I saw there had been an update, I tried to play again. The game crashes when I try to open it. ### 3/5 — Lots of fun on iPhone, unplayable on iPad *2024-02-05* Tons of fun on the phone, and even got some of the other available packs, but super frustrating on the iPad. Fix the playability on the iPad, and it would be a sure winner. ### 1/5 — doesn’t work on iPad? *2023-09-21* Installed on phone, works okay on phone. Installed on iPad, and game board extends beyond the screen, making gameplay impossible. Can’t get past the first board. ### 2/5 — Not for me *2023-08-17* Couldn’t get past the weird peeling animations over the squares, it was too busy. ### 1/5 — cant even make a move *2023-06-28* when i open the app ifs so zoomed in that i cant see. literally unplayable.i was trying to get a new color game after finishing I Love Hue and it's sequel and this was not that replacement. ### 4/5 — Stick with it *2021-02-20* This is much better game than it seems at first. If you are interested in color it’s worth taking some time with. I’m a photographer so I answer yes to that. Much of the UX is terrible. After an attempt at a level I get a message at the top: Target achieved by 37. The number changes but it never means anything to me. Sometimes the message is Target missed by 7. Some number again. Then a rating of 1-4 stars. The correspondence between the rating the preceding Target statement is unclear. Sometimes I have a star rating before I start a level. I have no idea what this means. Usually it’s one star. Nothing ever offers encouragement. The only thing that gives me a clear rating is if I go into leaderboards. But when I first go there, the message is always that I have “No friends” and that I’m “1 out of 1 player”. The next tab after friends is “Recents”, where I learn that I’m 1 player on this leaderboard, and again 1 out of 1 player. The third tab says “Global”, where I find I’m rated 66 in the level I just tried, with a score (maybe, it’s an unexplained number) of 115. Thinking I was exiting that screen I got taken to the all time high scores. Apparently I’m #22 with 1,441,550. I have no idea when or how I got those points, though after each level grouping there is a display of some numbers that I earned. It’s labeled experimental. Hue coins are required to see the “hint”, which presents a tiny version of the solution you can use to figure out where you’re going wrong. When you buy some it seems like you’re buying a lot, but they it turns out you use up several (5?) for each hint you display. Again discouraging. ### 1/5 — Eh *2020-08-26* There should be an option to turn off hints. Boring otherwise. ### 2/5 — Nice but ... *2020-03-15* Nice but I'm stuck on the level 1 summary. The graphics go beyond the screen and there seems to be no way to move to the next game. Too bad! ### 3/5 — ... its a great game, but the mechanics are.. *2019-10-05* Not good enough.. the shifting mechanism screws up the moves i make and takes away my score because I got to shift the tiles back to where they were hence adding more moves unnecessarily, I think it would be best to have a swapping tile mechanism rather than a shifting tile mechanism, also when I lift a tile, shift it and then place it back in the same spot ‘without letting it down’ it counts as a move that doesn’t make any sense.. also when I have several rows that have been corrected and I want to move a tile somewhere else it’s shifts those corrected rows creating more unnecessary moves, Think about it, in real life if you were arranging tiles, if you moved one tile to the other side of the Area wouldn’t you just swap tiles or would you take the time to shift all the tiles? it doesn’t make sense to do all that hence why I think a swapping mechanism is better but other than that this game is really cool if you’re not really concerned with the score B) bravo ### 5/5 — Educational and Enlightening! *2019-07-16* This is a really fun and fulfilling app! It teaches color theory in a more intuitive way. I feel like I am growing artistically because I’m more aware of how colors interact ...or don’t!! I feel challenged, but not stressed as I strive to perfect my skills. This is a well designed app and functions perfectly. ## Frequently asked questions about huedoku ### What is Huedoku?
